本文对全国大麦生态区划试验西宁试点三年结果进行了总结。从幼苗生长习性、冬春性、植株高度、单株穗数、穗粒数、空壳率、千粒重、株粒重、生育期等性状方面比较、研完了来自全国25个省(市、区)90个大麦品种在西宁生长发育情况及其差异。结果表明:(1)来自冬大麦区的品种的幼苗生长习性从南至北相应为直立、半直立、匍匐型。阶段发育特性相应为春性、半冬性、冬性。来自春大麦区的品种的幼苗生长习性多为半直立型,裸大麦区的品种多为直立型,全为春性;(2)冬大麦区内不同生态区的品种平均生育期随纬度升高而延长。春大麦区和裸大麦区品种平均生育期相近,不同类型品种的生育期以冬性最长,春性最短,半冬性居中。冬性、半冬性品种生育期长短与生育期内平均气温呈正相关,与日照时数呈负相关。春性品种则相反;(3)不同地区,不同类型的品种的经济性状亦有很大差异。
This paper summarizes the results of the three-year pilot project of barley ecological zoning in Xining. From the growth habit of seedlings, winter and spring, plant height, number of panicle per plant, number of spikelets per plant, shell percentage, grain weight per plant, grain weight and growth period, Growth and Development of 90 Barley Varieties in Xining and Their Differences. The results showed that: (1) The seedling growth habit of varieties from winter barley area was upright, semi-erect and creeping from south to north. The corresponding stage of development is spring, semi-winter, winter. Most of the cultivars from spring barley were mostly semi-erect, while those in bare barley were upright and springy. (2) The average growing period of varieties in winter barley increased with latitude And extend. The average growth period of spring barley and naked barley varieties is similar, and the growth period of different varieties is the longest in winter, the shortest in spring and the middle in winter. Winter and semi-winter varieties have a positive correlation with the average temperature during the growing period and a negative correlation with the sunshine hours. The spring varieties are the opposite; (3) The economic traits of different types and varieties are also quite different in different regions.
